<js code>
/*
example of initialization of an existing ol layer with mapquery:

    jQuery('#map').data("mapQuery").layers({
            type:'existing_ol',
            label:'Label that you prefer',
            legend:{url:'http://mapserver.edugis.nl/cgi-bin/mapserv?map=maps/edugis/cache/population.map&version=1.1.1&service=WMS&request=GetLegendGraphic&layer=Bevolkingsdichtheid_2010&format=image/png'},
            ol_layer:osm, // its an new OpenLayer.Layer object name
            });

 */
        existing_ol: function(options) {
            var o = $.extend(true, {}, $.fn.mapQuery.defaults.layer.all,
                    $.fn.mapQuery.defaults.layer.raster,
                    options);
            var params = {
                layers: options.ol_layer,
                transparent: o.transparent,
                format: o.format
            };
            if(typeof o.wms_parameters != "undefined"){
                params = $.extend(params, o.wms_parameters);
            }
            return {
                layer: options.ol_layer,
                options: o
            };
        },        

</js code>

it simply works,
any suggestion?

Thank you all

Hi Giuseppe,

the best way would be to add a new layer type. You would do something
like (just somewhere within your app):

$.extend($.MapQuery.Layer.types, {
    yournewlayertype: function(options) {
        // do some fancy stuff here
        return {
            layer: new OpenLayers.Layer.YourLayerType(),
            options: options
        };
    }
});

Then you can add a new layer to your MapQuery map with:
mq.layers({type: 'yournewlayertupe'});

It's just like the layer definitions for the layers that are already
defined in the ore. I hope you get the idea.

Cheers,
  Volker
